Title: Pickup apparatus for capacitive video disc players with transmission line tuned circuit
IPC: H04N5/93
Filed: 1974-03-26
Abstract: A video disc player, employing a stylus electrode to form a variable capacitance with a conductive disc coating, as geometry variations in the disc groove pass beneath the stylus, has a conductive stylus support arm which forms a transmission line with a surrounding arm housing of conductive material. The transmission line is capacity end loaded at the arm end remote from the stylus by a series combination of capacitances which include an air dielectric capacitor and a voltage variable capacitor. The air dielectric capacitor has a first set of plates suspended from the movable stylus support arm, and a second set of plates fixedly mounted on the housing and interleaved with the first set. The transmission line and associated capacitances form a tuned circuit with a resonant frequency subject to variation as the stylus-disc capacitance varies. The tuned circuit is excited with UHF oscillations from a fixed frequency oscillator operating at a frequency within an ISM-allocated band. As the resonant frequency of the tuned circuit varies, the resultant UHF oscillation amplitude variations are detected to recover the recorded information. A tuning control circuit responsive to the detector output adjusts the voltage variable capacitance to maintain a desired spacing between the oscillator output and the tuning range of the transmission line resonant circuit. The stylus support arm is subject to replacement in the housing without wiring disconnection or connection.

Filed: 1976-06-02
Abstract: A hammer mill has a plurality of hammer assemblies pivotally mounted about the periphery of a rotating rotor. Each hammer assembly has an arm portion connected to a pivot shaft and carrying a detachable head with slightly inclined impact surface.

Patent ES-8106975-A1 (ES)
Title: Video Disc Stylus Position Sensor System
IPC: G11B3/085
Filed: 1980-12-19
Abstract: To provide control signals allowing compensation of stylus tracking in eccentric grooves of a video disc 10, a stylus 11 carries an electrode 13 disposed between first and second electrodes 14, 15 fixedly mounted on a motor driven carriage 8 to which stylus 11 is compliantly mounted. The capacitances of the variable capacitors thus formed vary with the displacement of electrode 13, and hence of stylus 11, relative to carriage 8. In Figure 1, complementary a.c. signals V1, V2 are applied to electrodes 14, 15 so that the algebraic sum of these signals capacitively coupled to electrode 13 is indicative of the position of the stylus. The output signal V3 from electrode 13, via processing circuit 29, controls a motor 31 to move carriage 8 so as to restore electrode 13, and thus the stylus 11, to a null position. In Figure 8 (not shown), an a.c. signal which has been amplitude modulated by voltage variable impedances is applied to the first and second electrodes whereby the time average of the signal summed at the stylus related electrode is indicative of the stylus position.
